1.) f(x)=1.5x-0.4
[x=4, x=0, and x=-3]
F(4)=1.5*4-.4
F(4)=6-.4
F(4)=5.6 ANSWER.
F(0)=1.5*0-.4
F(0)=-.4 ANSWER,
F(-3)=1.5*-3-.4
F9-3)=-4.5-.4
F(-3)=-4.9 ANSWER.
JUST DO THE SAME REPLACEMENT FOR THE OTHER EQUATIONS.

The solutions to this problem set are actually quite simple.
All we need to do is plug in the given values of x into the function where they occur.

1) f(4)=1.5(4)-0.4
At x=4, the function is 5.6

f(0)=1.5(0)-0.4
At x=0, the function is -0.4

f(3)=1.5(3)-0.4
At x=3, the function is 4.1


2) h(4)=3%2F8(4)+2%2F3
At x=4, the function is 13%2F6


h(0)=3%2F8(0)+2%2F3
At x=0, the function is 2%2F3

h(3)=3%2F8(3)+2%2F3
At x=3, the funtion is 43%2F24


3) g(4)=-14(3)+5
At x=4, the function is -51

g(0)=-14(0)+5
At x=0, the function is -5

g(3)=-14(3)+5
At x=3, the function is -37


4) k(4)=3.2-5(4)
At x=4, the function is -13.6

k(0)=3.2-5(0)
At x=0, the function is 3.2

k(3)=3.2-5(3)
At x=3, the function is -8.6
